Donald Lyon Bentley is an American statistician and mathematician. [1] A doctoral student of biostatistician Rupert Griel Miller at the Stanford University School of Humanities and Sciences, [2] [3] Bentley graduated with a Doctor of Philosophy in Applied Mathematics and Statistics in 1962. [3] [4] He then taught at the Mathematics and Statistics Department of Pomona College in Claremont, California from 1964 to 2001, [5] becoming Lingurn H. Burkhead Professor of Mathematics, [6] an endowed chair, before retiring to become a professor emeritus. [1] He was also president of the Southern California Chapter of the American Statistical Association from 1987 to 1988, [7] and was named a Fellow of the American Statistical Association in 1990. [8]
Bentley is known locally for his role in creating Pomona College's tradition of revering the number 47. [6] [5] It began in the summer of 1964, [9] when two students, Laurie Mets and Bruce Elgin, conducted a research project seeking to find out whether the number occurs more often in nature than would be expected by chance. They documented various 47 sightings, and Bentley produced a false mathematical proof that 47 was equal to all other integers. The number became a meme among the class, which spread once the academic year began and snowballed over time. [10] Many Pomona alumni have since deliberately inserted 47 references into their work. [11] In the early 2010s, the college's clock tower would chime on the 47th minute of the hour. [12]
